Hello Admin,
I apologize for possible errors, I use a translator. I want to reissue a single POST request every 5 milliseconds or less. Frist I tried to repeat the request By Selecting the Session in Fiddler's Web Sessions list and Hold SHIFT+R. But the delay between the two consecutive requests was variable and sometimes reached 100 ms.
Then I tried FiddlerScript and Timer request following this topic:
https://groups.google.com/forum/?fromgroups#!searchin/httpfiddler/reissue/httpfiddler/8r9Hop7LMXg/0GROyv2HXWwJ
I set oTimer.Interval =5. But the problem remains. The timer accuracy was not good and the delay between the two consecutive requests was uncertain and sometimes reached 100 Ms.
Is there a simple solution.
Regards,

Hi Ryan,

Fiddler captures timestamps using the default system clock which is why the timestamps may appear inaccurate. The default system clock has a precision of 15.6 milliseconds This is the Windows default and is chosen this way to conserve power. There are a couple of different options to that may help with this which I have listed below. 

1. Enable high-resolution timers in the Fiddler options. 

2. Use a lower-level monitoring system such as Event Tracing or Network Monitor.

Please let me know if you need any additional information. Thank you for using the Fiddler forums.

Hi Thang,

 

 

Use this blog about getting started with FiddlerScript and refer to the section about targeting Sessions. There is an object called oSession that you could use to target sessions based on different criteria.
